TOBACCO-CARTRIDGE HOLDER.

Specification of Letters Patent.

Application filed April a, 1916. Serial No. 88,492.

bacco filler and a covering of rice paper or similar smokable material. If such cartridges are entirely inserted within an ordinary tobacco pipe the paper cover fits closely within the bowl of the pipe and may not be entirely consumed. The charred paper sticks to the interior surface of the pipe and interferes with the introduction of other cartridges unless carefully cleaned out. It has, therefore, been well known to make cartridges wherein the tobacco could be readily expelled from the paper covering into the pipe so that only the tobacco would be burned.

The object of the present invention is to provide a pipe or holder for a tobacco cartridge in which the bowl is shallow and only of sufiicient depth to firmly secure one end of the cartridge, the greater portion of the whole cartride being exterior to the holder so that the major part of the tobacco and of the paper cover burns freely in the open air.

Only a small portion of the cartridge extends into the bowl, just enough to securely retain the cartridge while being smoked and, accordingly, the cleaning out of the bowl ready for a new cartridge is facilitated.

A further object of the invention is to equip the cartridge holder with provisions which secure uniform draft throughout the entire extent of the cartridge, which prevent the fiow of nicotin into the stem of the holder and which enable both the nicotin and any saliva which may collect in the bowl of the holder to be discharged with the ashes when the holder is cleaned for the reception of a fresh cartridge.

The invention is illustrated in the accompanying drawings, wherein- Figure 1, is a perspective view of a car-v tridge holder embodying the invention. Fig. 2, is a longitudinal section of the cartridge holder. Fig. 3, is a plan view and Fig. 4:, a section of a modified form of cartridge holder. Fig. 5, is a section and Fig. 6, a plan view of a second modified form of a cartridge holder. Fig. 7 is a section of a third modfication of a cartridge holder.

Referring first to Figs. 1 and 2, the improved cartridge holder comprises a shallow bowl A, and a stem 13, the stem having a longitudinal passage 0, extending from the interior of the bowl to the end of the mouthpiece. The stem is illustrated as substantially perpendicular to the axis of the bowl, thus insuring the mouth of the bowl being substantially horizontal when in use, but any shape of stem may be employed which enables the mouth of the bowl to be sufficiently near the horizontal when in use to avoid the liability of particles of burning tobacco falling out when being smoked. A cartridge C, is indicated in Figs. 1 and 2. The bowl A, has an interior cup D, which has at its lower end a diaphragm b, which divides the bowl into two chambers. The chamber above the diaphragm b, is open mouthed and receives the cartridge. The

chamber E, below the diaphragm is in immediate communication with the stem passage a. This diaphragm b, is conical, or funnelform, extending upwardly from its periphery to the middle of passage 0, at its middle and highest part only. The mouth of the cup D, flares outwardly at d, to facilitate placing the cartridge in position to be smoked. By reason of this flaring mouth the inserted end of the cartridge is slightly compressed so as to maintain it securely in position. The tapering mouth likewise compensates for variations in the diameters of cartridges.

As illustrated in Fig. 2, the cartridge need not be inserted far enough to seal the top of the air passage 0. Whether the cartridge is thus inserted, or against the top of the diaphragm an annular channel exists above the diaphragm 7), extending entirely beneath the cartridge. Accordingly, when the user smokes the pipe, the air is drawn into the chamber below the diaphragm throughout the entire area of the cartridge thereby insuring a uniform burning of the cartridge throughout.

Any nicotin is collected in the channel a, above the diaphragm and below the air passage 0, so that it does not pass into the lower air chamber E, of the bow]. and hence cannot be drawn into the mouth of the smoker. Any saliva from the mouth of the smoker the bowl. It has an air passage 0, into the ash.

which passes into the chamber E, through the stem passage 64, collects therein and does not come in contact with the tobacco while the cartridge is being smoked.

As indicated in Figs. 1 and 2, the major part of the freshly inserted cartridge is outside of the holder and consequently pro duces the same kind of a smoke as a cigar or cigarette.

After a cartridge has been smoked the bowl will be turned upside down for the purpose of knocking out the ashes. When the bowl is thus inverted, any nicotin which is collected in the channel 6, will flow outwardly into the ashes and will be discharged with them. Likewise, any saliva which has collected in the chamber E, of the bowl will run into the funnel constituted by the tapering diaphragm b, and out through the air- Accordingly, the nicotin and the saliva will mingle with the ash and will be discharged therewith when the holder is cleaned.

Since only a small portion of the cartridge extends into the shallow bowl chamber above the diaphragm it is a simple matter to remove any particles of paper or tobacco which may adhere to the interior.

The cup D, is detachable from the bowl A,

and several ways of attachment are illusflange g,

headed pins p, which extend into the trated.

As shown in Figs. 1 and 2, the cup D, has a top flange 7", extending over the edge of the bowl, and it has a depending screw threaded which screws onto an external screw threaded portion of the bowl A. The lower edge of the flange is milled as shown at h, to facilitate screwing and unscrewing. The entire cup D,

is made out of a single piece of thin sheet metal stamped into the required shape. The cup is preferably of silver, for more expensive holders, and of aluminum or nickel for cheaper holders. Even nickel plated or tinned sheet iron may he used. The bowl and stem may be of wood or other materials from which pipes are made.

In Figs. 3 and 4:, the inner annular Wall of the cup D, is shown as screw threaded at i, to screw into the interior of the bowl which is internally screw threaded to receive it. The top flange f, terminates at the periphery of the bowl A, and its edge is milled at h, to facilitate inserting and removing the lining.

In the construction illustrated in Figs. 5 and 6, the top flange f, of the lining has bayonet slots m, which engage headed pins p, fastened to the bowl.

In Fig. 7 the downturned flange g, of the lining has bayonet slots m, which benglage ow In the construction shown in Figs. 5, 6,

and 7, the lin ng can be removed by giving including the diaphragm' b, the flanges f and 9,

it a partial turn so that the fixed pins 10, register with the mouths of the bayonet slots.

The holder may have a flat bottom as shofivn at F, in Fig. 5, so that it will sit uprig t.

The cup has a practically air tight fit in the bowl so that air is drawn into the chamber E, solely through the air passage 0.

The cup has the following advantages:

The funnel-form diaphragm of the cup facing upwardly catches the nicotin which accumulates near the outer edge of the funnel.

The cup prevents nicotin from intermingling with the saliva from the mouth and thus keeps this disagreeable mixture from getting into the stem of the pipe and then into the mouth of the smoker.

The space or chamber under the cup forms a cooling air chamber and acts as a depository for the saliva which comes from the mouth of the user through the pipe stem. A cool smoke is thus secured.

The diaphragm of the cup facing this air chamber E, being funnel-form will, when the pipe is turned over to discharge the ashes, cause the saliva which collects in the chamber to pass through the air hole in the apex of the funnel and mingle with the ashes and be discharged with them. Or, if the ashes have been first removed, the saliva will pass through the hole and be discharged separately.

The tobacco cartridge if inserted to the maximum extent will simply rest on the apex of the funnel-form diaphragm of the cup thus leaving an air space between the bottom of the tobacco cartridge and the inclined diaphragm of the cup on which the nicotin will collect and will be absorbed by the ashes of the tobacco. Accordingly, all of the tobacco will be consumed, without intermingling with the saliva or with the nicotin, so that the tobacco cartridge does not become wet and soggy.

Disagreeable odors are substantially decreased since they are largely due to fine particles of tobacco being drawn into the stem and mixing with the nicotin and saliva. By eliminating this strong odor, sweetness will be added to the holder.

In all of the modifications illustrated, both the bowl and the cup are shallow. It will be noted that in every case the depth of the cup is substantially less than the diameter.

Indeed, as the effective depth of the cup is determined by the apex of the diaphragm, it is less than half the diameter in each of the modifications illustrated.

Accordingly, when a cartridge of usual proportions is inserted the greater portion of the cartridge is outside of the bowl.

I claim:

1. A tobacco cartridgeholder comprising diaphragm a shallow bowl the depth of which is less than its diameter, in combination with a shallow detachable metallic cup of less depth than the depth of the bowl and fitting closely within the bowl with an external marginal flange at its mouth extending over the rim of the bowl, said cup having at its lower end an integral funnel-form diaphragm extending upwardly from the periphery of the cup toward the middle thereof said diaphragm having an air opening at its apex only, the cup and diaphragm being otherwise imperforate, this funnel-form dividing the pipe bowl into two chambers, a shallow upper chamber to receive the lower end only of the tobacco cartridge, this chamber having a nicotin collecting annular air channel at its periphery and a flaring mouth, and an air chamber below the diaphragm constituting a cooling and saliva collecting chamber.
